Clinical Significance
The barbiturate class of drugs are traditionally classified as sedatives and central nervous system depressants. Their principle uses are to calm the patient, produce drowsiness, and/or promote sleep. The test is a screening assay using a homogeneous enzyme immunoassay method of analysis. Therapeutic urine drug monitoring of the barbiturates is important for ensuring compliance to treatment strategies, as well as ensuring non-diversion for illicit purposes. Urine or oral fluid are the specimens of choice for routine monitoring of patients taking prescription drugs. Use of serum/plasma should be limited to anuretic patients, or where a patient's clinical appearance does not coincide with their prescribed medications. No single monitoring approach provides adequate information about the pattern or dose of patient drug use. Safest prescribing habits should include a combination of tools and laboratory test results to correctly detect drug use patterns. Urine drug test results equal to or greater than cutoff are reported as positive and results less than cutoff are reported as negative.
